most of them are but not all the later ones are made in labs
What else can I help you with?
Are all the elements naturally occurring manmade or both?
Not all the elements occur naturally; some elements are man-made.
How many elements start naturally in nature?
how may elements occur naturally in nature
How many known elements are there on earth are naturally made?
There are 92 naturally occurring elements on Earth.
Is it true that on earth 90 elements occur naturally?
Yes, at least 91 elements occur naturally: all of those with atomic numbers of 92 or less except technetium. This still means that the problem "statement" is true, because it does not contain any limiting word such as "only" to modify the number 90. (It is equally true that 2 elements occur naturally.)
Are the most naturally occurring elements metals?
No, the most naturally occurring elements are not all metals. The majority of elements on the periodic table are metals, but non-metal elements also occur naturally. Examples of non-metals include oxygen, nitrogen, and carbon.
WHAT ELEMENTS occur naturally?
Basically, all (or most) of the elements found in the periodic table, up to plutonium.
How many elements occur natural?
Elements 1-92 except 43 (technetium) and 61 (promethium) occur naturally. So, there are 90 naturally occurring elements.
How many elements on the periodic table occur naturally is it 18 92 98 or 118?
92 elements occur naturally on the periodic table.
Natural ocuring elements are?
All elements lighter than Uranium (atomic number: 92) occur naturally except for technetium (43).
How many elements shown in the periodic table do not occur in nature on earth?
118 total - 92 natural elements= 26 elements that do not naturally occur===========================
Why are most elements radioactive?
Most of the natural occurring (isotopes of) elements are NOT radioactive.Though most of all the known isotopes are radioactive but most of them do NOT naturally occur.
In what phase or state do most elements occur naturally?
Solid
